I would try to check RAM chips 512KB at a time, maybe one of your RAM chips are bad. Set the jumper to 512KB, start the computer and see it it works, if it does then try 1MB, you can try with the chips inserted or remove them all and try 512KB at a time.
Also, do you have any other RAM board installed?

Hey guys -

Are these the drams I need to buy to try and get this working?

Looks like they are the correct ones, BUT I don't think that ALL your DRAMs are bad, it could be the board. I have one of those A2091s and it has the same problem, it doesn't recognize the RAM.
